The Rising Stick Alarm (RSA) is U.S. Coast Guard accepted. It satisfies 46 CFR 39.20 3(b), 39.20-(b), as well as OPA 90 regulations for overfill devices and is suitable for use on ABS classed vessels. The RSA utilizes the ERL L-40 alarm Reed switch which carries a UL approval for use in hazardous cargo locations.
Personnel are not exposed to hazardous cargo vapors on the tank top when using the reliable RSA Liquid Level Gauge. The hazard of overfill spills is greatly reduced when properly using the RSA. The RSA alarm operation can be checked by removing the weather cap, and lifting the stick until the High Level and Overfill alarms annunciate.
- EASY INSTALLATION
Simply bolt the RSA to an 8″ Class 150 flanged pipe stand located at or near the geometric center of the cargo compartment. The deck opening must be large enough for the 7″ dia. float to pass through.
- HEAVY DUTY CONSTRUCTION
All welded components are 300 series stainless steel. Powerful NEODYMIUM #38 rod magnets are used to insure superior coupling strength between the CERAMIN #8 float magnet and the tri-colored gauge rod. The tri-colored gauge rod, color coded to industry standards, is hermetically sealed by design, to provide extended service life.
- SIMPLE, RELIABLE OPERATION
Stainless steel linear slide floats actuate the liquid level switches. The high level switch actuates (opens) when the cargo compartment is 95% full. Subsequently the overfill switch actuates (opens) when the cargo compartment is 98% full. With the Rising Stick Alarm connected to the loading dock’s alarm/shutdown system and/or to barge mounted alarm annunciator panel, the risk of overfill spills are significantly reduced.
